Currently I am learning Back-End development with Rust.

My strongest language at the moment is TypeScript, specially in back-end development with NestJs, Express or Fastify. Apart from TypeScript I know Python and Rust as well.

GraphQL API development with NestJS (TypeScript) or Async-Graphql (rust). I have slowed down on Data Science, but with a refresher I am willing to collaborate on ML as well.
